Hi,
the example in chapter 10.3 [1] seams to be a very handy thing, but I
couldn't reproduce it (testing it on the output chain).
I'm using v1.4.3.1/2.6.29.6 does this require v1.4.4/2.6.30?

(btw: thanks for this wonderful paper)
iptables -A OUTPUT -d 10.10.97.1/255.255.255.253 -m iprange --dst-range
10.10.97.1-10.10.97.7 -j REJECT
this should match on 10.10.97.1,3,5,7 but matches only 1 and 3
iptables -A OUTPUT -m iprange --dst-range 10.10.97.1-10.10.97.7 -j LOG
--log-prefix "SKIPPED: "
nmap -sP 10.10.97.1-7
log:
SKIPPED: ... DST=10.10.97.2
SKIPPED: ... DST=10.10.97.4
SKIPPED: ... DST=10.10.97.7 <--
SKIPPED: ... DST=10.10.97.5 <--
SKIPPED: ... DST=10.10.97.6
best regards,
Christoph A.
